CVE-2012-5977 asterisk: Denial of service through exploitation of device state caching (AST-2012-015)
Last modified: 2013-01-30 02:40:25 EST
A denial of service flaw was found in the way Asterisk, an open-source PBX software, performed management of its internal device cache in certain circumstances. A remote attacker could use this flaw to cause the asterisk executable to consume excessive amount of system resources via repeated anonymous calls with different sources of the particular anonymous call (forcing the asterisk binary continually to add new devices into its device cache).
This issue affects the versions of the asterisk package, as shipped with Fedora release of 16 and 17. Please schedule an update.
This issue affects the version of the asterisk package, as shipped with Fedora EPEL 6. Please schedule an update.
